Biography Summary

Dr. Li studies strategies to improve indoor air quality and reduce occupant exposure to airborne pollutants in residential and commercial buildings. Her research is focused on smart ventilation and filtration systems that use sensors to automate system operation. She also investigates the impact of occupant activities on indoor pollutant sources and explores the effectiveness of occupant-centric approaches to mitigate these sources. In addition, Dr. Li is working with an interdisciplinary team that includes experts in engineering, epidemiology, medicine, and knowledge translation to improve indoor air quality in community spaces and congregate settings and explore the relationship between indoor air quality and public health policy and guidance. Dr. Li serves as a member of the Indoor Air Quality Advisory Group of the Ontario Society of Professional Engineers, which is working to create guidelines for indoor air quality.
